10/17/2023 0 Comments 2 1/2 dredge nozzle.![]() The new sluice is a single-stage box, however, with the woven wire classifier, the long rubber damper, miners moss, rubber ribbed matting, and the latest riffle designs, you will not be disappointed in the fine gold recovery. The sluice box has been shortened by 8” for a total of 40” in length. The smaller, lighter, more compact 4” is ideal for packing into remote areas and is also great for quick one-day outings. The other drawback of a 2 or a 2.5 is that these usually are not equipped with air.This New 4” dredge is specifically designed to be lighter and more portable than our standard model. So if a 2" will move 2 yards per day then a 3" will move 4 yards.Ī 4" dredge is a good balance between large capacity and compact size and can be moved and operated by one dude. Rule of thumb on size difference is: with every inch of nozzle size you increase, you double your production capacity. It took us a full week to dig a 10 yard hole with the 3". My first real dredge was a 3" and that damn thing nearly worked me to death because if the rock wont fit up the hose, you have to move it by hand. When people first get into this they tend to start small but ALWAYS move up to larger gear. Buy the biggest dredge you can afford that is small enough for you to handle and legal in your area. A lot of people ask me this question and my answer is the same. There wont be much difference and your first dredge should not be a new one unless you have plenty of disposable income.
